Draining Procedure
Important: Drain and measure as much of the refrigerant
oil as possible from the rear head ports and the front head compressor drain bolt
hole of the REMOVED compressor.
- Remove the compressor crankcase oil drain bolt and drain the refrigerant oil
from the crankcase and rear head ports into a clean, graduated container.
- Rotate the compressor shaft to assist in
draining the compressor.
- Measure and record the amount of oil drained from the removed compressor.
This measurement will be used during installation of the replacement
compressor.
- Inspect oil drained from removed compressor. Refer to
Air Conditioning Compressor Oil Diagnosis
.
- Properly discard the used refrigerant oil.
- Clean the graduated cylinder.
Important: Drain and measure as much of the refrigerant
oil as possible from the rear head ports and the front head compressor drain bolt
hole of the NEW compressor.
- Remove the compressor crankcase oil drain bolt and drain the refrigerant oil
from the crankcase and rear head ports into a clean, graduated container.
- Rotate the compressor shaft to assist in draining the compressor.
Balancing Procedure
Important: The refrigerant
oil in the A/C system must be balanced during compressor replacement.
The replacement compressor is shipped with the total system capacity of refrigerant
oil.
- Refer to the amount of refrigerant oil recorded during the compressor removal.
- If the amount of oil recorded from the removed compressor is less than
or equal to 75 ml (2.5 fl. oz), add 75 ml of the new PAG
oil back into the new compressor through the compressor oil drain bolt hole.
Notice: Refer to Fastener Notice in the Preface section.
- Install the compressor oil drain bolt.
Tighten
Tighten the bolt to 15 N·m (11 lb ft).
- Rotate the clutch driver three times to lubricate the internal compressor
components.
Important: If additional A/C components are replaced
during compressor replacement, add the PAG oil directly to the A/C compressor to compensate
the A/C system.
- If necessary, refer to
Refrigerant System Capacities
.
